Complexity Collapse

framework
Societies don't always decline slowly — sometimes they get so complex to maintain that they suddenly crash and simplify.
Who they are

'Complexity Collapse,' a framework from archaeologist Joseph Tainter.

What they do

The engine uses it as a model for how civilizations fail.

How it works

As a society adds complexity it gets diminishing returns; once the cost of maintaining that complexity outweighs its benefits, the system doesn't gently wind down — it simplifies catastrophically.

Why it matters

It's a lens the engine uses to understand sudden systemic breakdown rather than gradual decline.

The engine's record — word for word
Tainter. Diminishing returns on societal complexity. When cost of maintaining complexity exceeds its benefits, systems simplify catastrophically.
